Ethiopian 787 tatt fyr på LHR?

Så 787 har altså bare dårlig karma og man kan der regne med "freak accidents" som Boeing ikke er skyld i? Jeg kjøper ikke helt den forklaringen. Enheten det nå tok fyr i var jo koblet til noe annet i flyet og der gikk det muligens ukurrante signaler/spenninger.

Never ending story.
JAL 787 returnerer til Boston.

Tilfeldighetene vil kanskje ha det til at dette gikk bra og ikke ble total katastrofe?

Early findings show that the fire, which burned through the fuselage of the plane and filled the cabin with acrid smoke, could not have been easily extinguished, or quickly detected while the plane was airborne.

Det var en indikasjonslampe på at en fuelpumpe var i ustand som kom på.

Maskinen var, ifølge rapporten, 'powered down', dvs koblet til bakkestrøm, men ikke slått på. Hvis jeg forstår det rett vil det da ikke gå noen form for strøm til denne peileren. Den bruker vel forøvrig bare strøm tll lading av batteriet?

Dårlig karma eller ikke - at dette skjedde på en 787 var nok helt tilfeldig.

How it can be fixed depends on how extensive any weakened area is.

Weber said there is a well-established procedure for applying a composite patch, either bonded or fastened to the existing skin. But he said it’s possible the damaged area is too big to be patched.

In the worst case, he said, Boeing might have to replace the entire aft fuselage section, a single barrel-shaped piece measuring 19 feet in diameter and 23 feet long.

In fact, this option could prove easier than patching. That’s because any fix will entail proving to the FAA that the repair is sound.

Frank Abdi, chief scientist and founder of Long Beach, Calif.-based AlphaSTAR, which specializes in structural modeling and analysis of composite materials, said that to apply a substantial patch Boeing would have to do a computer simulation of the repair then “prove by analysis and by test that such a thing is possible.”

Retired Boeing manager Ed Wilson, who worked with composites on the B-2 and 777 programs, said that replacing the entire back end could well be the quickest fix.

Patching it, he said, “you’ll spend more time screwing around trying to convince regulators that it’s

Siste utgave av Randy's blog opplyser at batteriet ikke er koblet til flyets strømforsyning.

I know some of you are interested in how the ELT works. While ELTs aren’t necessary for normal airplane operations, their primary purpose is to alert and guide rescue crews to the location of an airplane in the event of an accident. They are found in airplanes across the industry as available options selected by airlines.
An ELT is powered via its own battery with no help from the airplane. The ELT interfaces with the airplane via wires connected to the flight deck so that the pilot can activate the transmitter if necessary. Turning on the transmitter doesn’t transfer any power to the unit. There is a co-ax cable from the unit that connects to the antenna, located on top of the fuselage. If an ELT needs to be removed, it is a straightforward process that takes about one hour.

U.K. investigators who examined the device, called an Emergency Locator Transmitter (ELT) and made by Honeywell, found that the internal wires connecting the battery to the ELT had been trapped and pinched when the cover was reattached as the batteries were inserted, according to two sources with knowledge of the matter, one inside Boeing and one outside.

In photos of what was left of the device, “You can clearly see the two wires crossed over each other. It’s quite evident the wires show evidence of being smashed,” one source said.

Ser ut som maskinen kan repareres og de nå også har startet arbeidet

Så den med stillas rundt halen på søndag, står ved cargo/rampe syd for 27L og vest for T4 på Heathrow, med høyre bakside mot banen så det var ikke mye å se.

I følge Aviationweek skal arbeide være over halveis med å reparere maskinen, som blant annet innebærer å bytte ut det brente området

Boeing engineers repairing the Ethiopian Airlines 787-8 stranded at London Heathrow Airport for five months since it was badly damaged by an emergency beacon fire have replaced a large section of the upper fuselage structure and refitted the tail unit as part of efforts to return the aircraft to service early next year

Motorene ble startet på denne idag, så snart så flyver denne fuglen igjen, heldigvis

Da er jammen flyet kommet seg på vingene igjen. Ute å flyr en 150 min test før den skal lande på MSE.

British aviation investigators reported Wednesday that a 2013 fire on a Boeing 787 Dreamliner started in a battery for the plane's emergency locator transmitter — a finding that triggered recommendations to improve safety on similar battery-powered equipment on planes.

The Air Accidents Investigations Branch said in a report that crossed and trapped wires under the battery compartment created a short circuit on the Ethiopian Airlines-operated plane parked at London's Heathrow Airport on July 12, 2013.
